New Patent Filing – PPL1 Mystery Revealed Through our investigation we discovered that Pitney has recently published a patent on the use of monepantel (an aminoacetonitrile derivative) for the treatment of cancer (Source: http://patentscope.wipo.int/search/en/WO2013138863). Aminoacetonitrile derivatives (AADs) are a class of anthelmintics effective against drug-resistant nematodes. Although PAA has not confirmed our investigations, it appears that the only marketed monepantel product is Zolvix®, produced and distributed by Novartis Animal Health (Source: http://zolvix.com/monepantel/). Recall that PAA’s disclosed lead product is an anthelminthic which is being targeted to the treatment of both veterinary and human cancers.
